pinctrl: berlin: guard sub-directory with CONFIG_PINCTRL_BERLIN

2015-12-01T09:39:26+00:00

CONFIG_PINCTRL_BERLIN is more suitable than CONFIG_ARCH_BERLIN
to guard the drivers/pinctrl/berlin/ directory.

pinctrl: berlin: fix BG2CD field widths

2015-10-16T14:42:48+00:00

The previous register layout was incorrect, many of the fields having
fewer bits than were needed to represent all their modes. The new layout
is taken from the bootloader source of a BG2CD device.

pinctrl: berlin: fix my family name spelling

2015-10-16T14:28:57+00:00

My family name contained an accent when I submitted the
Berlin pinctrl series in the first place. There was an
encoding issue when the series was applied. Fix this.

pinctrl: berlin: add explicit dependency on OF

2015-10-16T14:20:04+00:00

Berlin pinctrl drivers depends on CONFIG_OF. This patch adds
this dependency explicitly.

pinctrl: berlin: select the pinctrl driver according to the SoC used

2015-10-16T14:18:27+00:00

This patch prepares to remove the pinctrl driver selection from the
mach-berlin Kconfig. To do so, bool is replaced by def_bool.

pinctrl: berlin: add the berlin4ct pinctrl driver

2015-10-16T14:13:20+00:00

Add the pin-controller driver for Marvell Berlin BG4CT SoC, with definition
of its groups and functions. This uses the core Berlin pinctrl driver.

pinctrl: berlin: Make berlin pinctrl driver visible if COMPILE_TEST=y

2015-10-16T14:12:17+00:00

It is good to allow berlin pinctrl driver to build with COMPILE_TEST, so
make the it menu visible when compile-testing.

pinctrl: berlin: introduce berlin_pinctrl_probe_regmap()

2015-10-16T14:10:57+00:00

This is to prepare for the next berlin4ct support, where we won't use
simple-mfd any more.

Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2015-06-26T18:54:29+00:00

Pull ARM SoC driver updates from Kevin Hilman:
 "Some of these are for drivers/soc, where we're now putting
  SoC-specific drivers these days.  Some are for other driver subsystems
  where we have received acks from the appropriate maintainers.

  Some highlights:

   - simple-mfd: document DT bindings and misc updates
   - migrate mach-berlin to simple-mfd for clock, pinctrl and reset
   - memory: support for Tegra132 SoC
   - memory: introduce tegra EMC driver for scaling memory frequency
   - misc. updates for ARM CCI and CCN busses"

pinctrl: make pinctrl_register() return proper error code

2015-06-10T12:49:52+00:00

Currently, pinctrl_register() just returns NULL on error, so the
callers can not know the exact reason of the failure.

Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some
-ENOMEM on error of pinctrl_register(), although the error code
might be different from the real cause of the error.

This commit reworks pinctrl_register() to return the appropriate
error code and modifies all of the pinctrl drivers to use IS_ERR()
for the error checking and PTR_ERR() for getting the error code.
